So have you been rotating the tires? I would put the spare tire on and see what happens to it.

It is time for 6 or 7 new tires.

You should not add a new tire to a dulley with 40K miles. Maybe a steer tire. I vote for inconsistent psi at some point, it doesn't take long and then doesn't correct.

Your tires are old. Replacement cost could be peanuts compared to a blow out. I'm not saying it will happen but the increased risk factor is there.

Based on what you've posted replace all of the tires and you will be good for another 40K miles and 7 years. [emoticon]

New tires are coming. Just want to rule out anything that may cause a new tire to get torn up

I wear outside rear tires faster too, so they get rotated amongst the rear axle.

I think it’s from driving on highways with ruts from cars with studded tires. The inner wheels ride over the ruts. Outsides take all the load.


Your logic is off some. The tire with most load has best traction. The weight will cause more wear because tread is compacting and expanding as it contacts pavement. But the real wear happens as the tire that is less solid on pavement slips.

I’ll try to answer all questions. The pressure is consistent over all the tires. These are the OE tire since the truck was new so they are consistent with the DOT dates. I do not drive the truck much on a daily basis, mostly towing the RV. I have noticed this inconsistent wear for a few years so I don’t believe it’s the age. I don’t want to throw a new tire at it if there is a known issue that I can resolve before changing the tires as another poster suggested.


After I wore tread off a tire way to fast I started to measure tires before I put into dual service. Have seen half inch difference same size and brand. Running side by each that smaller tire would slip that half inch every revolution. And as that slip causes wear, the tire slips more, wears faster.

What makes you think tires are original?

ZERO reason to touch the rear tires on a DRW, unless you drive like Mario Andretti. My DRW tires have 43k and the only rotation I do is the fronts side to side with the "rotation the same". This requires breaking the tires from the rims. I have 6/32" left on all six tires.

OP you are lucky to get 40k out of the RAM OE tires.

Like I said make sure everything is flat on the wheels.

I have the same with my Ford. I understand this is normal due to weight distribution. I never do it, but they say to rotate the tires so they wear evenly.
